摘要:
A method includes detecting a first event and executing a first procedure to identify a sensor offset in response to detecting the first event. The method further includes determining, via a computing device, whether the sensor offset was measured during the execution of the first procedure, scheduling a second procedure to execute in response to detecting a second event if the sensor offset was not measured during the first procedure, and scheduling the first procedure to execute in response to detecting a subsequent occurrence of the first event if the sensor offset was measured during the first procedure.
摘要:
A hybrid powertrain system includes a transmission operative in a plurality of operating range states. An operating range state can be secured, including assigning each operating range state to a group that can be verified, monitoring a transition path from a first to a second operating range state, and monitoring a torque equation for the present operating range state.

A system for robust fault detection in an electrically variable, hydraulically controlled transmission includes independently monitoring hydraulic pressure within a hydraulic control circuit and electric machine rotation for detecting clutch state faults.
摘要:
A diagnostic system for a hybrid vehicle comprises a processor module and a motor control module. The processor module outputs a first seed value. The motor control module controls torque output by an electric motor of the hybrid vehicle and outputs a key value based on the first seed value. The processor module outputs a second seed value after receiving the key value, and the motor control module selectively diagnoses a fault in the processor module based on a comparison of the second seed value with the first seed value.
